Chris,
no, I didn't look at the import table -
I will look into it when I am back from work...
Logging the calls has of course the advantage
that you can check for some interesting
parameters....
For example, I discovered that Croc makes many
calls to grColorMask( FALSE, FALSE ), which
means it doesn't render color at all (only depth???).
Does this make sense?
Is there a way to do this in RRedline (e.g.
InstallDstBuffer() with NULL as buffer?, or do
I have to create a dummy-buffer?). At home
I could not open the RRedline Reference manual (?),
have to check it here now...
Regarding the call to grSetErrorCallback, I have
to verify it - yesterday evening, I found at least
two errors in my initial logging macros:
grDrawPlanarPolygonVertexList is of course wrong,
and means grRenderBuffer instead!!!!
The second one I can't remember right now, but
it's not that important or obvious...
